AXLE BOX r[he object of our invention is to make a substantial and comparatively light axle box. `This object we attain by making the box from rolled, 4pressed or forged steel shapes asl' sembled and welded together. An -axle box in the manner which will be described herein can be readily manufactured at a low cost.

In the accompanying drawing: l

Fig. 1 is a perspective view of our lmproved Fig. 2 is a sectional elevation on the line 22, Fig. 3; and

` Fig. 3 is a sectional plan view on the line 3 3, Fig. 2.

The axle box shown in the drawing 1s of a shape to receive a roller-bearing of a standard type, but it will be understood that the box can' bev of any design desired without departing from the essential features of the 90 invention.

The body l() of the box is made of two-half sections 12-12, shaped in the present instance to receive a roller-bearing shown by v dotted lines in Fig. 2. The inner raceway of this roller-bearing is secured to the axle and the outer raceway fits against a shoulder formed by an internal rib 13 of the box. In the present instance the outer end of the box is rounded as at 14 and the opening in the end is closedby any suitable lid or cover. v

The rear end of the box is o en for the axle and its connected parts, and as a slight internal'lange 15 and an external flange 16. A dust ring is secured to the rear of the box as shown by dotted lines, Fig. 2.

The two sections 12-12 of the body of the box are .made from a rolled strip of'a cross-section similar to the cross-section of the box and bent to form one-half of a cylinder. The two sections, when assembled as shown in Fig. 1, are welded togetherin any suitable manner. -l

The only finish necessary is a grinding on the two abutting edges of the sections of the box, and the seat for the lid and for the dust ring. l

In order to reinforce the body lof the box and to vprovide pedestal guides for the box,

50 the two rings 17 --17a are formed as shown in Fig. 1. These rings are cut from a rolled blank, unched and sha ed as shown.

The ront ring 17 in t e present instance is shaped to lit a portion of the curved surface 14 of the body as shown in Fig. 3, and has a pedestal way 18 at each side of the shape shown in the drawing. The rear ring 17n fits the'rear portion of the body and has a pedestal way 18l at each side. `When the rings 17-17 are forced onto the body of the box, the two sections 12--12 are drawn close together and the entire structure welded in any suitable manner.

Located between the two ring sections 17--17L is an equalizer seat 20, made of pressed sheet metal and provided with a rib 19 which extends into a notch in an equalizmg beam of anysuitable type.A On each side of the seat 20, and preferablyV located between the seat and the rings, are chafing plates 21. Between the inner ring 17 and the fiange 16 are spacers 22. The seat 20, chafing plates 21 and spacers 22 are welded to the structure.

Where the upper section of the body differs materially from the lower section, then the sections can be made from rolled stock differing in form. n While the body of the box as described above is made of two sections formed from rolled strips bent into shape, the sections may be made from plates bent or forged into'the shape desired, and the rings may be made in the same manner.

An axle box ofthetype described can be cheaply andl accurately manufactured and is lighter and stronger than the ordinary cast axle box. The box illustrated is particularly adapted as a roller bearing axle box for heavy rolling stock.

An axle box in which the body of the box is made in two sections, with two rings encircling the body and spaced apart, each ring having vertical ribs forming pedestal guides, and an equalizer plate on the upper portion of the box between the rings, and a chafng plate between the equalizer plate and each ring,` the whole being welded together.
